In order to extend the lifetime of the internal relays and prevent unwanted switching noise, it is recommended
to use free wheel diodes (1N4007), if a DC voltage is used for the regulation. If an AC voltage is used for the
regulation, it is recommended to use a varistor. The diode/varistor must be placed across the terminals of the
pilot motor/external regulation relay coil.
